Read before use: the information below describes traditional and informational uses — it does not replace the advice of a healthcare professional. In case of doubt, pregnancy, breastfeeding, ongoing treatment, or use in children, seek advice before use.

Enhanced precautions for this plant: Scientific data on this plant are very limited; it is recommended to consult a healthcare professional before any use. Avoid all use in pregnant or breastfeeding women, as well as in young children, due to lack of safety data. Do not exceed the occasional traditional uses described; avoid prolonged use without advice from a qualified practitioner. In case of doubt regarding botanical identification, refrain from use: several similar species from the Yucatán may be confused.

Decoction — Dried bark and leaves

Traditional Mayan decoction

The bark and leaves were traditionally simmered gently in water, then allowed to cool before being strained. This preparation, reported by traditional healers of the Yucatán, requires the advice of a professional before any use, due to lack of precise data on dosages. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Compress — Crushed bark

External application as poultice

Fresh or dried bark was crushed and then applied directly to the affected skin area, sometimes moistened with a little warm water. This traditional external use has not been scientifically validated and should be considered with caution. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.

Where to find it

Sourcing the plant

This plant is not cultivated outside its native range; it is found wild in the dry forests of the Yucatán and is rarely, if ever, available in the European herbal trade.

Harvest season

When to harvest it
